I believe that in order to find HITLOD keywords, you do not have to search for them. They will just come to you just like how great artists and inventors suddenly come up with a brilliant idea.
Going about my day to day experiences, I have discovered some great keywords. To cite an example, I searched the internet for the real story behind the movie 21 after I watched it. (This is what I usually do when I watch a great movie. I normally want to know the real story behind the movie since Hollywood often loosely base their script on the real story)
The movie 21 is based on the book "Bringing Down the House: The Inside Story of Six MIT Students Who Took Vegas for Millions" by Ben Mezrich. The entire book may be considered fictional, however the events that transpired in the book are loosely based on the life of a brilliant MIT student who was a member of the MIT Blackjack Team named Jeffrey Ma.
The MIT blackjack team was group of students and ex-students from the Massachusetts Institute of Technology, Harvard University, and colleges who used counting cards techniques to win in the game of blackjack.
The MIT blackjack team earned an estimated $3 million to $5 million U.S dollars. Their operation very organized and run like a real business. Casinos worldwide was beaten in the game of blackjack with their simple counting cards techniques.
"Blackjack is a beatable game," This was the motto of the group. To win at blackjack all you have to do is use simple math and employ simple counting cards techniques.
After I read several articles on the MIT black jack team and listened to the interviews of Jeffrey Ma. I realized that people would start to emulate them by gooogling "black jack", "counting cards in blackjack", "counting cards", "how to count cards" or other similar keywords. I tried several keyword combinations and the best one I could find was "counting cards." I became hooked on the "counting cards" fever myself, read some articles and watched some videos on how "counting cards" was done.
As of to date, the keyword "counting cards" has been cited in 443,000 sites. The graph in Google trends shows a spike. Most likley this occurred somewhere after the movie was released on March 2008 in theaters.
People only began searching in volume for the keyword "counting cards" in 2008. This tells us that interest in the keyword "counting cards" was because of the movie 21.
"Counting cards" may be a good HITLOD keyword and it's being high trend could only be temporary. After several years, months or even weeks I believe people will stop searching for the "counting cards" keyword after interest in the movie has waned.
Despite that observation, "Counting cards" is still a HITLOD keyword as of today. So sieze the opportunity ! As the movie is still new, people will still search for the "counting cards" keyword. If you have properly optimized the keyword, no doubt it will bring tons of traffic to your site.
